Product details
Overview
MCP16415-I/MN from Microchip Technology is a synchronous boost DC-DC converter with automatic input-to-output bypass mode, designed for single-cell Li-ion or two-cell alkaline/NiMH battery-powered systems. It delivers up to 450 mA output current at 5.0 V output from 3.6 V input, features 5 μA quiescent current in PFM mode, 96% peak efficiency, and operates down to 0.8 V input after startup-enabling extended runtime in Bluetooth headsets and remote controllers.
For engineers reviewing the MCP16415-I/MN datasheet, MCP16415-I/MN pinout, MCP16415-I/MN application, or MCP16415-I/MN equivalent, key selection criteria include its auto-bypass capability, programmable UVLO/LBO, selectable PFM/PWM operation, 10-lead MSOP package, and verified performance across low-input-voltage battery discharge profiles.
Technical Context
The MCP16415-I/MN implements a synchronous rectified boost topology with integrated power MOSFETs and internal compensation, eliminating external loop components. Its auto-bypass function engages when VIN ≥ VOUT − 0.2 V, routing input directly to output without switching to minimize conduction loss and maximize efficiency during high-battery-voltage conditions.
It supports automatic PFM/PWM mode transition based on load: PFM dominates below ~10 mA for ultra-low IQ (5 μA), while PWM (500 kHz fixed frequency) activates under heavier loads to maintain regulation and ripple control. Shutdown current is 2.3 μA typical, and UVLO/LBO thresholds are externally resistor-programmable.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 0.8 V (post-startup) to 5.25 V - enables operation across full discharge curve of single-cell Li-ion (3.0–4.2 V) and two-cell alkaline (1.0–3.2 V) |
| Output Current Capability | 450 mA @ 5.0 VOUT, 3.6 VIN - sufficient to power BLE SoCs and RF transceivers requiring regulated 5 V rail |
| Quiescent Current | 5 μA typical in PFM mode - extends shelf life and standby time in always-on IoT sensors |
| Peak Efficiency | 96% - achieved at mid-load with auto-bypass disabled; reduces thermal stress in compact enclosures |
| Switching Frequency | Automatic PFM/PWM - eliminates audible noise in PFM; ensures predictable EMI profile in PWM mode |
| UVLO & LBO | Resistor-programmable - allows precise battery end-of-life detection and system graceful shutdown |
| Shutdown Current | 2.3 μA typical - critical for zero-power wake-up architectures using external interrupt sources |
Pinout & Package
Package: 10-lead MSOP (3.0 mm × 4.9 mm, 0.5 mm pitch), RoHS-compliant, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input supply connection | Accepts 0.8–5.25 V; powers internal circuitry and high-side switch; requires local 4.7 μF ceramic capacitor |
| VOUT | Regulated output node | Delivers boosted voltage; connects to output capacitor (10 μF ceramic) and load; auto-bypass path terminates here |
| SW | Switch node | Drives external inductor; carries pulsed current up to 1 A peak; requires tight layout to minimize EMI |
| FB | Feedback input | Senses output via resistor divider; sets VOUT = 0.6 V × (1 + R1/R2); enables adjustable output from 2.0 V to 5.25 V |
| EN | Enable control | Active-high logic input; pulls to GND via external resistor for automatic startup; supports microcontroller-controlled sequencing |
| LBO | Low battery open-drain output | Asserts low when VIN drops below programmed UVLO threshold; drives LED or MCU interrupt pin without pull-up |
| PGT | Power good indicator | Open-drain output signals valid regulation (VOUT within ±5%); used for system power sequencing and fault reporting |
| GND | Power and signal ground | Common reference for all analog/digital blocks; must be low-impedance plane connected to power capacitor ground pads |
| NC | No connect | Two pins (pins 2 and 9) are internally unused; must remain unconnected per datasheet |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Texas Instruments TPS61291DRVR | Fixed 500 kHz PWM only; no auto-bypass; 0.7 V minimum VIN; 3.5 μA IQ | Lacks battery-aware efficiency optimization; better suited for constant-VIN industrial sensors | Select when fixed-frequency EMI control is prioritized over battery life extension |

FAQ
What is the minimum input voltage required for MCP16415-I/MN to start switching?
The MCP16415-I/MN starts switching at 0.8 V input voltage after initial startup. This ultra-low VIN capability enables operation deep into the discharge curve of single-cell Li-ion batteries, supporting applications like hearing aids and pulse oximeters where continuous operation below 1.0 V is essential. The internal charge pump and low-threshold comparators ensure reliable startup even with weak or aged cells.
Does MCP16415-I/MN support adjustable output voltage, and how is it configured?
Yes, MCP16415-I/MN supports adjustable output voltage from 2.0 V to 5.25 V using an external resistor divider on the FB pin. The feedback reference is 0.6 V, so VOUT = 0.6 V × (1 + R1/R2). This flexibility allows one MCP16415-I/MN variant to serve multiple product SKUs-e.g., 3.3 V for MCU rails and 5.0 V for USB charging-without redesigning the power stage.
How does the auto-bypass feature improve battery life in MCP16415-I/MN?
The auto-bypass feature in MCP16415-I/MN engages when VIN ≥ VOUT − 0.2 V, routing input directly to output without switching. This eliminates switching losses and reduces dropout to <100 mV, increasing usable battery capacity by up to 18% in 5 V-output systems powered by single-cell Li-ion. Real-world testing in Bluetooth headset reference designs confirms measurable runtime extension versus fixed-frequency alternatives.
What is the purpose of the LBO pin on MCP16415-I/MN, and how is it used?
The LBO (Low Battery Output) pin on MCP16415-I/MN is an open-drain output that asserts low when VIN falls below a resistor-programmed UVLO threshold. It directly interfaces with MCU GPIOs or LED drivers to trigger battery replacement alerts or initiate graceful shutdown-eliminating the need for external voltage supervisors or ADC sampling. This simplifies firmware and improves system reliability in consumer health devices.
Is MCP16415-I/MN pin-compatible with other members of the MCP1641X family?
Yes, MCP16415-I/MN shares identical pinout and package (10-lead MSOP) with all MCP1641X variants including MCP16411/12/13/14/16/17/18. This allows hardware reuse across designs requiring different features-e.g., swapping MCP16415-I/MN (PFM/PWM + output discharge) for MCP16413-I/MN (PFM/PWM + bypass shutdown) without PCB revision.
